    Several rare earth activators (Dy3+, Sm3+, Eu 3+) doped nanocrystalline and microcrystalline Sr2Gd xY7.9-x(SiO4)6O2 are synthetized by sol-gel method. The luminescence and the energy transfer properties from Gd3+ to Ln3+ are studied. The results show that the energy transfer efficiency from Gd3+ to Ln 3+ is in the sequence Sm3+ < Eu3+ < Dy3+ in the nanocrystals, in the microcrystals the sequence is different, and compared to the counter microcrystals, the value of energy transfer efficiency in the nanocrystals from Gd3+ to Ln3+ is lower.
